Abstract

We have developed a multi-point Thomson scattering system with double-pass configuration for the TST-2 device and have installed new collection optics for the same. Temperature and density can now be measured simultaneously at four points by using four fibers and four polychromators. Herein, we present results of off-axis temperature anisotropy measurements performed with this system, in which no temperature anisotropy beyond the error bar was observed for ohmic plasmas.
